engadget has published the first unofficial pics of what appears to be the much-rumored PlayStation phone, which looks like the result of mating a Sony Ericsson Xperia X10 with a PSP Go.

According to the report, the (obviously) prototype device – codenamed “Zeus” – sports a touchscreen display in the 3.7 to 4.1-inch size range with a minimum WVGA resolution. On the front are four basic face buttons with a slider sporting the familiar PlayStation face buttons, shoulder buttons and a long multitouch touchpad in place of the analogue joysticks.

The phone also reportedly features a 5-megapixel camera and will be powered by a 1GHz Qualcomm MSM8655 processor with 512MB of RAM and 1GB of ROM. Although there’s no Memory Stick slot, there is support for microSD cards. The prototype is apparently running Android 2.X but engadget predicts it will ship with Android 3.0 (Gingerbread) when released... probably in 2011.

Responding to calls that the images and details are fake, engadget is adamant its claims are true, saying the information comes from multiple, trusted sources including some people closely connected to the project.

There has been no official announcement from Sony – "Sony Ericsson does not comment on rumors, speculation or unannounced products."
